ACV Motor BM102-152n 53429085

This product is a replacement motor for a fan used in a modulating premix boiler or burner. It is mounted on the fan housing and drives the impeller. Motor speed is the primary means of controlling the firing rate. The model is BM102-152n, manufactured by ACV, and identified by SKU 53429085.

Choose a replacement by comparing the original part number, the fan model, and the control interface used by the burner control. The motor must have the same voltage rating, control mode (mains, PWM, or 0–10 V), and connection pattern as the original. Verify the impeller size and outlet orientation of the existing fan assembly. Install the motor on the fan housing, ensuring it drives the impeller correctly. If the original used PWM control, a mains-only motor will not work.

Typical failures include worn bearings, impeller imbalance due to deposits, a failed run capacitor, and speed feedback errors. The boiler may report an airflow fault when feedback is lost. Check the motor bearings, the impeller for deposits, the capacitor, and the speed feedback signal.
